UNITED STATES! PATENT @FFIQE SAMUEL FAVINGER, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO HIMSELF AND ABSALOM BARNED, OF SAME PLACE.

SMUT-IVIACHIN E.

Specification of Letters Patent No. 29,215, dated July 17, 1860.

To all whom it may concern:

Be it known that I, SAMUEL FaviNenR, of the city of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Smut-Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon.

My invention consists, firstly in a fan blower arranged in respect to the grain hopper, certain'passages, and a casing containing a bur, substantially in the manner described hereafter, so that the light refuse particles and imperfect grain may be separated from that which is sound and perfect, prior to the latter being scoured. Secondly, in the peculiar construction of a tapering bur with V shaped projections having V shaped ribs for the purpose of effectually scouring the grain. Thirdly, in a plate with a ribbed surface and a bar with brushes arranged in respect to the bur and its casing in the manner described hereafter so as to rub the grain after it has been acted upon by the bur.

In order to enable others to make and use my invention I will now proceed to describe its construct-ion and operation.

On reference to the accompanying draw ing which forms a part of this specification Figure l, is an exterior view of my improved smut machine. Fig. 2, a sectional elevation. Fig. 3, a plan view, and Fig. 4, a plan view of a detached portion of the machine.

Similar letters refer to similar parts throughout the several views.

A is the base plate of the machine to which are secured the three columns B,B,B,sup porting an upper plate C an intermediate plate D and a box E containing the vanes F of a fan blower, to be more particularly described hereafter.

To the plate C is secured a circular chamber G with curved sides containing any suitable number of vanes I-I, connected to or forming a part of a central hub h which is secured to the vertical shaft J, 'the latter turning at the top in a box a secured to the cap I of the chamber G and the lower end of the shaft turning in a step o on the base plate A. To this vertical shaft J is secured a tapering block or bur K of the form of frustum of a cone, but having a series of V shaped projections each of which is formed of a number of minor projections of a similar shape as best observed on reference to Fig. 4. To the bottom of this bur K is secured a circular plate /c on the upper face of which are formed V shaped projections as seen in Fig. 4.'

To the under side of the plate is secured a bar d having on the under side brushes c c bearing against the upper surface of the plate D which has also a series of V-shapcd projections.

The plate D has a central opening j" bounded by a iange which projects above t-he upper surface of the plate for a purpose which will be rendered apparent hereafter.

The bur K its circular plate 7u and bar Z are inclosed by a tapering casing L the upper end of which is secured to the under side of the plate c and the lower end to the edge of the plate D.

M is an inclined box or chamber communicating at the top through a passage mi with the interior of the fan chamber G and at the bottom through an inclined passage a. with the interior of the casing L. The passage m communicates with a hopper p also with the interior of the casing L through the inclined pipe g also with a vertical chamber N, in front of which is a sheet of wire gauze s and the lower end of which is furnished with a spout t, as is also the lower end of the chamber M with a similar spout u, the interior of the fan box E being separated from the chamber M by a perforated plate V.

P is the shaker supported at one endv on legs fw resting on the cap I of the chamber Gr the opposite end being jointed to the upper end of a lever Q which is hung to a bracket R secured to the plate G, the short arm of the lever being connected by a rod x to an eccentric y on the vertical shaft J.

The shaker P consists of a box having an upper and lower chamber separated from each other by the perforated partition 2 best observed on reference to Fig. 3, the upper chamber having an inclined passage 3, and the end of the lower chamber being situated directly over the hopper p.

Motion is communicated to the vertical shaft J by a strap 4 passing around a pulley on the said shaft and around a pulley 5 on a vertical shaft 6 which turns in brackets 7 secured to the columns B, see Fig. 3, motion being communicated to this shaft from any adjacent driving shaft.

A sliding door 8 is arranged to obstruct more or less the communication between the fan chamber Gr and the passage m, and a similar sliding door 9 is arranged to present a greater or less obstruction at the points of communication between the chamber M and passage m with the vertical chamber N.

Operationz-The grain deposited in any suitable elevated receptacle is allowed to fall into the outer end of the hopper P by the agitation of which the pieces of straw and chaff pass over the perforated partition 2 and through the inclined passage 3 while the grain passes through the perforations of the partition into the lower chamber of the hopper down which it slides into the hop per p. As the grain drops from the latter it is subjected to the blast created by the revolving vanes II so that all light particles which may have passed through the perforations of the hopper as well as light and imperfect grains are blown through the passage m and against the wire netting s the small light particles passing through the meshes of the latter and the imperfect grains or screenings passing down the vertical chamber N and through its spout t into any suitable receptacle. It will be seen that by this arrangement the grain is deprived of much of the oal, dust, and foreign substances before it can gain access to the intcrior of the casing L. The sound grains which pass into the latter casing through the pipe g are struck by the angular projections of the tapering block or bur K from which the grains are projected against the casing with such force as to rebound from the latter and be again struck by the projections this action being continued until the grain falls onto the plate la where it is again struck by the angular projections on this plate, thrown out against the casing and finally 'falls onto the upper ribbed surface of the plate D over which it is rubbed by the brushes e of the bar Z until it finds its way down the passage a.

It will be evident that the severe agitation to which the grain is subjected by the rapidly revolving tapering block or bur with its V shaped projections must insure that thorough and effectual scouring so necessary in all smut machines.

As the scoured grain, smut, and other refuse particles pass from the pipe n over the perforated plate o the whole is subjected to the blast from the fan F which drives the smut and other refuse up the pipe M and out in front of the machine while the cleansed grain passes through the spout n into any suitable receptacle. Y

That I claim as new and desire to secure by Letters Patent is* l. rIhe fan chamber Gr, with its vanes I-I when arranged in respect to the hopper p, the passages m and g and the casing L containing the bur K, substantially as and for the purpose herein set forth.

2. The peculiar construction of the tapering block or bur K with its V shaped projections having V shaped ribs as and for the purpose specied.

3. The arrangement of the plate D with its ribbed surface the bar Z with its brushes and tapering bur and casing L for the purpose set forth.

In testimony whereof7 I have signed my name to this specification, in the presence of two subscribing witnesses.

SAMUEL FAVINGER.
